Circle Line is proudly billed as Singapore’s first modern-day creature feature, which is bold, because after watching it, you realize the real monster wasn’t in the tunnels — it was the script all along.
On paper, this thing sounds like a tight, claustrophobic thriller: last subway train of the night, wrong turn into abandoned tunnels, contact lost, a rescue operation above ground, and a mysterious creature snacking on commuters like they’re dim sum samplers. That should be lean, tense, and terrifying.
Instead, Circle Line feels like someone tried to mash together Train to Busan, Jaws, and an MRT safety ad, then exported the file as “low resolution, emotionally compressed.”
Off the Rails, On Every Level
We start in a Southeast Asian city with an automated subway system that, apparently, is run by a combination of bad code and worse luck. The last train of the night veers off-course into abandoned tunnels because… error. That’s it. No elaborate sabotage, no sinister corporation, no unknown hack. Just “oops, the system broke.”
You’d think this would be an opportunity to explore themes of overreliance on automation, accountability, governance, all that juicy sci-fi irony. Instead, the movie treats it like a plot convenience: “We needed you underground, so there you go. Don’t ask questions, the creature is waiting.”
The passengers onboard are a sampler pack of trauma and awkwardness:
-
Yi Ling (Jesseca Liu), single mother haunted by her husband’s death in an accident.
-
Lucas, her young son, there to be endangered and occasionally adorable.
-
The estranged teen daughter of the subway’s chief engineer, for that extra dose of family drama.
-
A handful of side characters who might as well be walking name tags that say “Creature Snack #1–#5.”
The setup screams “human stories in a crisis.” The execution whispers “we had 90 minutes and some CG budget; let’s just wing it.”
The Creature Feature with Commitment Issues
Let’s talk about the monster. In a creature feature, this is your star. Your main event. Your big bad. Circle Line’s creature, however, feels like it wandered in from a different movie, got lost, and decided to stay out of politeness.
Its design is… fine. Not iconic, not laugh-out-loud terrible, just mid. You never get that sense of awe, dread, or “holy hell, what is that?” you want from the first reveal. Instead, it looks like the developers of a mobile game were told, “We need something that looks dangerous but not too weird; we’re on a schedule.”
The movie also can’t decide what kind of creature it wants this thing to be. Stealthy stalker? Rampaging beast? Territorial animal? Symbol of human negligence? It sort of cycles through all of the above depending on the scene. Sometimes it’s clever, sometimes it’s clumsy, sometimes it can take a beating, sometimes it retreats faster than a Wi-Fi signal in a lift.
It has no clear rules, which means we don’t know what to fear. Fear works best when we understand the stakes and the capabilities of the threat. Here, the monster is just a vaguely toothy plot device that appears whenever the script remembers it’s supposed to be a creature feature.
Tunnel Vision Storytelling
The biggest sin Circle Line commits is not being aggressively bad — it’s being aggressively average in the most frustrating way. Everything you’d expect to happen usually does, in the most straightforward manner possible.
Characters split up when they obviously shouldn’t. The command center loses contact at the worst possible time. People freeze, scream, or fall exactly when the creature needs them to. If you’ve seen even two genre movies in your life, you can play Bingo with the clichés. You’ll win. Early.
Yi Ling’s trauma about her husband’s death is meant to be the emotional backbone of the movie. In practice, it’s wheeled out whenever the film wants to remind you that this is not just about a monster, okay? There are feelings. You get flashes of her past, her guilt, her fear — but they’re never fleshed out beyond the basics. It’s tragedy as a convenient accessory: “Look, she’s sad. Now back to running and screaming.”
The estranged engineer-dad-daughter subplot has similar potential: a family torn apart by work, duty, and disaster, forced to reckon with their issues in crisis. But again, it gets the shorthand version. A couple of sharp exchanges, a reveal or two, and then right back to “we’ll fix this later, if we’re still alive.”
The result is a film that gestures at depth without actually diving into it. Like a train that keeps rushing past interesting stations but refuses to stop because it’s late for its next jump scare.
Command Center: Now with Extra Pointlessness
While the passengers are being hunted underground, the train system’s central command is busy “mounting a rescue operation.” At least, that’s the idea. In reality, these scenes mostly involve people staring at screens, pointing at signals, and saying things like, “We’ve lost them” and “We must bring them back.”
There’s a lot of urgent typing. Some stern faces. A bit of blame-shifting. But very little of it actually affects what’s happening underground in any meaningful way. The command center could have been an email that said, “You’re on your own.”
Instead of building a cool parallel track — above ground strategy vs below ground survival — we get what feels like filler: reaction shots instead of action, discussions instead of decisions.
If you’re going to cut away from your monster movie, give us something worthwhile: moral dilemmas, tough calls, genuine tension. Instead we get control room cosplay.
Characters with All the Depth of a Platform Announcement
The cast is genuinely solid. Jesseca Liu is capable of real emotional heft. Peter Yu, Andie Chen, Patrick Lee — these are not amateurs. But the script gives them very little to work with beyond “survive, emote occasionally, repeat.”
Yi Ling’s entire arc boils down to: guilt > fear > resolve. Lucas is Cute Child in Peril™. The estranged daughter is Rebellious Teen with Feelings™. The other passengers are mostly fodder, with just enough personality sketched on them that you’re supposed to vaguely care when they’re eaten, but not enough that you remember their names ten minutes later.
It’s like the film knows it should care about its characters but doesn’t have the time or inclination to actually build them, so it gives them one defining trait each and calls it a day.
Horror Lite, Suspense-Adjacent
For a creature feature, Circle Line is weirdly timid. The attack scenes are functional but rarely thrilling. The camera often cuts away at the best moments or sits too far back to capture real visceral impact. There’s no truly memorable kill, no “I will never sleep again” moment — just a series of mildly upsetting altercations with a digital beast.
Suspense is similarly undercooked. The movie occasionally sets up potentially tense situations — tight spaces, low visibility, people trapped — but rarely milks them. Scenes resolve quickly, often predictably. The editing doesn’t lean into dread; it just keeps the plot moving.
You never get that sustained “oh no, oh no, oh no” feeling that a good monster movie can deliver even with a tiny budget. You mostly get “oh, okay, we’re running again. Cool.”
Singapore’s First Creature Feature Deserved Better
To be fair, Circle Line is not a total trainwreck (sorry). It’s competently made. It tries to blend emotional drama with genre thrills. It’s clearly made with some pride and ambition. But you can’t hang an entire marketing push on “first modern-day creature feature” and then deliver something this toothless.
The setting — a Southeast Asian city, a subway system, abandoned tunnels — is underused. The creature is generic. The themes are half-baked. The tension is sporadic. The characters are sketches.
It’s the cinematic equivalent of a soft launch: technically out there, technically working, but not something you’d want to shout about from the rooftop of Suntec City.
Final Stop: Mild, Messy, and Mostly Forgettable
In the end, Circle Line feels like a decent student of the genre that never quite graduates. It knows the homework: you need a monster, a confined environment, human drama, and a race against time. It just can’t quite pull any of those elements into something sharper, scarier, or more memorable.
If all you want is background monster content while you scroll your phone, this will do the trick. If you were hoping for Singapore’s answer to Jaws on the MRT, this is more like Mildly Annoyed Lizard on the Wrong Platform.
The movie promises life and death on the line. What you actually get is 90 minutes hovering somewhere in between — not quite alive, not quite dead, just stuck in the cinematic equivalent of a service disruption.
